Modder fits Steam Deck motherboard into Game Boy shell with custom cooling and planned AMOLED display
↗
A modder has built a working Steam Deck system inside a Game Boy form factor, with a custom display adapter and BIOS mod still needed to complete the screen integration.
This project demonstrates that Steam Deck hardware can be repackaged into much smaller enclosures using undervolting and compact cooling solutions. The display integration approach mirrors existing community mods like DeckHD, showing an emerging pattern of hardware-level modifications to Valve's platform that require custom PCBs and firmware changes.

A functional Steam Deck motherboard, battery, speakers, and face buttons fit within original Game Boy dimensions.
A 30x7mm fan with a custom 3D-printed mount and undervolting achieves 70 to 80°C gaming temperatures.
A custom adapter PCB and BIOS mod are still required to integrate a 1200x1080, 90Hz AMOLED panel originally intended for VR.
